“…In addition, Sangaré et al (2013) claim that a nursery medium consisting of aged bark and Canadian peat (1:1 v:v) with an addition of 30% coconut has a better relative gas diffusivity about 47%. Peats from the Nordic and the Baltic countries shrink under the influence of lime at a dose above 4 g m -3 (Maher and Prasad 2004). In our own research the number of rooted cuttings in the commercial Hartmann medium was lower by 25% when compared with the number of rooted cuttings in the Ceres medium.…”

Lavender cotton (Santolina chamaecyparissus L.) shoot cuttings, obtained from two-year-old mother plants, were rooted in five different media under an unheated foil tunnel. Two ready-made and widely recommended media were used: Hartmann peat substrate and Ceres peat-coconut substrate, as well as three prepared mixtures: high peat + mineral soil, high peat + perlite and high peat + sand. The influence of medium type on the number of rooted cuttings and the quality of the root system was assessed for two cultivation times during a three-year study after eight weeks from the date of cutting. As far as the ready-made rooting substrates are concerned, Ceres peat-coconut substrate turned out to be better when compared with the Hartmann substrate. The number of high quality rooted cuttings was larger when media containing high peat mixed with either mineral soil or sand were used in comparison with the mixture of high peat and perlite.

“…These properties can vary widely according to conditions under which the peat is produced (Bragg, 1990;Michel, 2010). For instance, younger or less decomposed peats tend to have a higher water holding capacity than older more decomposed deposits (Maher and Prasad, 2004;Schmilewski, 2008a). Crucially, this inherent variability provides a flexible material which can be used across a wide range of horticultural sectors.…”

The modern agricultural system is wasteful, with Europe generating some 700 million tonnes of agricultural and food waste each year. In the context of the agri-food chain, the 'circular economy' aims to reduce waste while also making best use of the 'wastes' produced by using economically viable processes and procedures to increase their value. In this paper we will try to frame the key issues associated with food waste into the emerging bioeconomy and circulareconomic mode, suggesting that these three concepts are intertwined, and considering them unitarily might provide win-win solutions that minimize wastage, promote income growth and job creation, and prompt sustainable local development. In terms of performance and economic considerations, peat is in many ways an ideal constituent of soilless growing media. Peat has become the material of choice throughout plant production systems from propagation to saleable 'finished plant' material. However, the extraction of peat has well documented negative impacts on the environment; arguably the most important of these is the release of stable, sequestered carbon into the active carbon cycle, thereby exacerbating climate change. During the last 20 years, peat extraction has come under increasing scrutiny throughout Europe and particularly in the UK. This has generated an abundance of studies examining a diverse range of alternative materials (as compost, vermicompost, digestate, biochar). In the selection of new materials, environmental considerations have become as important as performance and economic cost. In this context there has been a justifiable emphasis on organic materials derived from agricultural, industrial and municipal waste streams. For future urban sustainability it is necessary to develop integrated processes, which can be part of a circular bio-economy. However the challenge still remains of simultaneously recycling the nutrients from the waste. The greenhouse horticulture applied to nutraceutical species is the ideal sector for improving the conversion rate of organic waste into food and health friendly products. On farm composting/vermicomposting/pyrolysis/anaerobic digestion and the use of the end-product to the partial substitution of peat in nursery activity allows reducing the environmental and economic costs in the production of potted plants.
